If you put each equation into the form y = mx + b the answer should be clear.
They have the same slope...
is it 5? would that mean that it only has one solution?
If two lines have the same slope they are parallel if they don't lie on top of each other.
so it does'nt have a solution at all then?

Do parallel lines cross?
no
Then no, there is no solution.
